28-Piece Natural Basalt Hot Stone Set with Bamboo Box

Master Massage 28-Piece Natural Basalt Hot Stone Set with Bamboo Box

The Master Massage 28-Piece Hot Stone Set is a versatile professional collection of 100% natural black basalt massage stones for therapists who want more flexibility than a compact 18-piece set without moving immediately to a large 40-, 50-, 60- or 70-piece collection. The set combines large, medium and small flat oval stones with 4 specialist pressure-point stones, giving you a broader selection for massage work, suitable placements and focused techniques. A natural bamboo storage box keeps the complete collection organised between treatments.

✔ 28 natural basalt massage stones – versatile professional collection
✔ 8 large + 12 medium + 4 small oval stones
✔ 4 specialist pressure-point stones for more focused massage work
✔ 100% natural black basalt
✔ Smooth shaped and polished surfaces
✔ Natural bamboo storage box included

Why Choose the 28-Piece Hot Stone Set?

The main advantage of the 28-piece set is its balance between stone variety and manageable set size. Whereas the 18-piece collection concentrates on large and medium oval stones, the 28-piece version adds smaller stones and four narrower pressure-point stones. This gives the therapist more choice when matching the stone to the body area and intended working technique. At the same time, 28 stones remain comparatively straightforward to heat, clean, count and store – particularly useful for practices that do not need the extensive reserve capacity of a 50-, 60- or 70-piece set.

Four Stone Sizes & Shapes for Greater Flexibility

The collection contains four clearly differentiated groups of basalt stones, providing a more versatile setup than a basic two-size set.

8 Large Flat Oval Basalt Stones

Approx. 7.5 × 5.7 × 2.5 cm each

Large working stones with a broad contact area. The manufacturer's suggested allocation includes stones for larger areas such as the back and thighs.

12 Medium Flat Oval Basalt Stones

Approx. 6.6 × 5 × 1.8 cm each

A versatile general-purpose size suitable for several treatment areas. The manufacturer's suggested allocation includes arms, palms, feet and calves.

4 Small Flat Oval Basalt Stones

Approx. 3.8 × 3 × 1.8 cm each

Compact stones for smaller placement areas where the larger oval stones would be impractical.

4 Pressure-Point Basalt Stones

Approx. 7.5 × 3 × 1.8 cm each

Narrower specialist stones that expand the collection beyond traditional flat oval massage stones and allow more focused, controlled contact.

Total: 8 large + 12 medium + 4 small + 4 pressure-point stones = 28 natural basalt stones.

Natural Basalt for Hot Stone Massage

All stones in this collection are made from natural black basalt, a dense volcanic rock commonly used for hot stone massage because it can absorb and retain warmth effectively. According to Master Massage, the stones are shaped and water-polished to create smooth, even working surfaces. No wax or artificial dye is specified as part of the stone finish. Because basalt is a natural material, differences in colour, grain, surface character and exact dimensions are normal and make each stone slightly individual.

Suitable for Compact Professional Hot Stone Routines

With 28 stones, the set provides greater scope for simultaneous placements and stone rotation than the smaller 18-piece collection while remaining significantly more compact than the largest professional sets. As a practical orientation, it is well suited to shorter to medium-length routines of roughly 30–45 minutes, depending on technique, number of simultaneous placements and how frequently cooled stones are replaced. Treatment duration should not be treated as a fixed specification. Therapists who use extensive full-body layouts or require a large number of replacement stones throughout longer treatments will generally benefit from a larger collection.

Natural Bamboo Storage Box Included

The full 28-piece collection is supplied in a natural bamboo storage box. This keeps the different stone sizes together and makes it easier to organise the collection between treatments. After use, clean the stones according to your professional hygiene procedure and allow them to dry completely before returning them to the storage box.

18-Piece or 28-Piece Hot Stone Set?

The difference is not simply ten additional stones. The 28-piece set also provides a broader range of stone sizes and specialist shapes.

Choose the 18-piece set if:
✔ you want the most compact Master Massage basalt collection
✔ large and medium oval stones cover your main requirements
✔ you mainly perform shorter or focused applications
✔ you want supplementary stones for an existing collection

Choose the 28-piece set if:
✔ you want large, medium and small oval stones
✔ you want specialist pressure-point stones included
✔ greater placement and working flexibility is important
✔ you want more stone rotation without buying a large set

28-Piece or Larger Hot Stone Set?

A larger set becomes useful when you need more stones available simultaneously or want greater reserve capacity during longer routines.

• 28 stones: Compact professional versatility with four stone sizes and shapes.
• 40 stones: More stones for regular full-body work and increased rotation.
• 50 stones: Broader professional collection with additional reserve stones and specialist stone types.
• 60–70 stones: Extensive collections for longer routines, larger layouts and maximum stone availability.

Stone count alone should not determine your choice. Compare the number, dimensions, shapes and stone materials included in each set.

Choose the Right Hot Stone Heater

The 28 basalt stones should be heated in a suitable temperature-controlled professional hot stone warmer. The collection is easier to accommodate than larger 50–70 piece sets, but usable heater capacity depends on the internal reservoir dimensions as well as the number and arrangement of the stones.
